Hey SC from NY: Read the SC law as written. No exclusions for that "one drink". The law is not about the drink, it is about the place, where liquor/drinks are sold. As I said before, if you end up in a perfect storm, you have killed someone with a firearm that you should not have had on you based on where you were coming from. If you can explain that away--good luck. IMO, if there is one reason I like to CC it is at night as I leave a restaurant to go to my car--which I cannot do under SC law.
